Our pendants can be customized for the right tactile feel for manual operation, or mounted in one of our many mounting brackets to achieve durable limit switch operation in your equipment.

  • Military grade (neoprene cover) per MS39058
  • Industrial grade (Santoprene cover)
  • Meet IP68
  • UL available
  • Normally open, closed, SPDT
  • Custom length Wire leads, cable or coil cord terminations

Maintained Contact Switches – Pendant Style

Maintained Contact SwitchesMaintained contact pendants are available with the same options as the momentary units. Extremely durable construction in a compact package make these unique problem solvers.
